IMPROVEMENT IN SIGNS.

I, FRANK WALKER, of Windsor, in the county of Windsor and State of Vermont, have invented certain Improvements in Alterable- Labels or Signs, which render them more desirable and valuable than those of previous invention, and of which the following is a speciflcation:

Nature and Object of thc Invention.

My invention relates to that class of alterable labels or signs77 in which the letter-plate is struck up from sheet metal and the letters are printed on card-board or thick paper 5 and Description of thc Accompanying Drawing.

B shows a sectional view of my improved label or sign-plate,77 illustrating its diii'erence from others. The curved line d d indicates the curved or convex plateback; the line c c, the sliding plate or slip of card-board; and the line ff, the. continuous line of detached letters, pressed upon and bellying out through the operation of the curved back and the Inovable spring-plate. O represents the face view of the same reduced in size, wherein the colored letter-cards f f f are set and extended on the movable spring-back c c, showing in the spaces between said letter-cards the inserted back e' e e of same color.

The sliding sheet of card-board will constantn ly operate as a spring its entire length, to keep all the letters severally within the letter-plate., and regular, true, and harmonious in appearance.

In ease several sign-plates are used in connection-a thing often desirable-it is necessary, for the beauty of the sign, that the several words or lines contained in the several plates be of various lengths; and, to accomplish this, it is necessary to extend the letters or words more or less, as the case may be, by leaving space between said letters or Words; and here the spring-plate is found most serviceable, for the difficulty of otherwise holding the letters in place-especially those on Anarrow cards, such as periods, commas, &c.-is

readily seen. Moreover, for contrast and beauty, letter-cards of different colors may be used in the several plates, in which case the movable back may be changed to conform to the color of the letter-card used; thus, the back being like the letter-cards thereon, said lettercards may be extended as desired and still present the appearance of being printed on one continuous slip of card-board.

I am aware that alterable labels or signs are old, and such I do not wish to claim; but

What I do claim as my invention is- A plate, adapted to alterable labels or signs, having a curved or convex back, combined with a slip or plate of card-board, to operate as a spring, for the purpose of keeping the detached letters in position within the lips ofthe letterplate, substantially as shown and described.
